• Show whether an active span is running on and blocking the main thread or whether it's running in a threadpool with tokio::task::spawn_blocking. --color-top/color_top gets split into two colors, color top main and color top threadpool. The former is used when the task is running on the main thread, the latter is used when it's offloaded to the threadpool.
• Colorblind friendly default colors (http://www.cookbook-r.com/Graphs/Colors_(ggplot2)/#a-colorblind-friendly-palette):
  • color top blocking: #E69F0088
  • color top threadpool: #56B4E988
